How many cells can an Astro 210 handle?

I have an Astro 210, no longer listed, and have lost the instructions. The max. voltage is 25V on the unit itself. I want to run 20 X 2400SCRs. I'm going to be close to the listed max. Has anyone used 20 cells? Did the magic smoke come out?

Bernard Cawley and Doug Ingraham are two who will know the answer for you. Bernard will probably respond; or you can go to the Controller column here on Ezone and email him directly. I don't have Doug's email address anymore; Bernard might if you do not.
